IMPROVEMENT YIn METALLIC BINDINes'I-'QR TEXTILE FABRICS.

" The Schedule referred to'in these Letters Patent ndmaking part of the same.

To all whom fitmaj/ concern:

Be it known that 1, JAMES TWAMLEY, of New York, of N ew York county, in the StateI of New York,

have inventedA certain newand. useful Improvements inMetallic' Bindingfor'lextile Fabrics; and I do hereby declare-that the following is a full and exact description thereof, reference being had to the accom- `panying ,drawing `making part of this application.

My invention relates ito I a new method f of attaching metallic bindings to' the 4tips or ends of suspenders, garters, 85e. p Y

4Previous to `my invention ithasA been customary to tip the ends of Suspenders, garters, &-c., with a bind# kingor. edging of sheet metal, in order that the ends of such textile fabrics Inight not easily fretor ravel, ,and to make such al'ticles of wear more durable and desirable. But'in all instances in which such articles have been manufactured the metallic bindings or tips have been secured to the fabric either by'simplc cir cular indentations, or, more generally, by making ya series of small corrugations crosswise of the binding,

or in the direction= in which the tendency to slip ott would he. i The objectionto this method of attachment has been that the bindings are so easily pulled f off that thc advantage intended to be gained by the use of them is in a great measure lost.l

My invention has forit's object to provide a method of attachment ot' the metallic binding to the textile fabric which `will insure the lasting, retention of the b parts together, while atthe same `time thel manufacture is not rendered any `more expensive, andthus produce lall articles requiring metallicfbinding in a much more desirable-condition than that in which they have heretofore been putV into the market; and to these ends,

My invention consists in formingthe metal binding with points cut in it in such a direction, and after# wardbending these points to impinge on the textile fabi-Ic, in such a manner that the binding will be securely fastened Vtogthe fabric, and in suehamanner that any strain Vexerted to detach the .parts will have a-tendeucy to vmoreiseeurely interlock or fasten them togethenas willl be hereinafter moreA fully explained.

'Io enable those' skilledl in the art to make my in vention, I will proceedjto describe it more minutely,

referring byletters to the accompanying drawing, in which I,

Figure I is an elevation, and Figure 2 a section of a portion of a suspender-strap or garter, having `the end tipped with metal, accorcii'ng to my invention. y

Figures and 4arc detail views, in elevation and cross-section, of lthe metal binding, drawn on van Menlarged scale, andV illustrating thev peculiar form 4of thev securing points or barbs. Y

In the several ligures the same., partlwilll be found designated bythe same'letterof reference. p

A illustrates part of a suspender-strap, ladies -gar ter, or other article of a fibrous and textile nature,

to the'end of which is applied the metallic. binding or tip B, as clearly illustrated.

The hindi-ng B is, as usual, made to conform inl contour to the shape of the edge of the material which is to'be bound, and is placed over said edge in the usual manner, and as shown, but, inlieu of being clamped or `fastened onto the material A in the customary manner, by small corrngations, as shown.

at the f diagram in the drawing, it has cut in it several barbs or points, I 2 3, '&c., which are so arranged, with their points toward the outer and their root-steward the inner edgeot the binding, that, when -bent inward, sofas to impinge upon and partially penetrate the material A, (as seen at tigs. 2 and 4,) they. will take a rm lbite or hold on the material, and securely fastener interlock the metallic binding B and material A together. Vlt will be understood that the pointsior barbs `1 2 3 will bc further cramped or buckled into the material by any pull on the parts' which would have a'tendency. to separate the binding from the materiahand that thus any tendency to pull these part-s' away from each other will only 'tend to more securely interlock or fasten them together. Of course the number, precise shape, and size of the securing barbs 1 2 3 may be varied to suit the character of the article, and not material to the carrying out of my invention, so long as a sufficient number ot' securing points be used, of a propel' size, and of such a shape that the operation will be such as I have ex`` plained and illustrated. I

In the manufacture of metal-bound articles the barbs Inay be either cntv in the binding, when it is made, and afterward bent as the binding is applied to the article A, orthe cutting and bending of the barbs may be done simultaneously as the binding is applied tothe article, by suitable machinery for that purpose.

The operationsof forming andbending and putting plane portion of the metal binding opposite, as shown.-

Having explained my invention so that those skilled can make use of it,

`What I claim as new, and desire to secure by Letters Patent, is 'I A metallic binding for textile fabrics, united thereto b. by means of barbs turned toward the fold of the..

metal, ysubstantially as and for the purposes set forth. Intestimony whereof, I have hereunto set my hand and seal, this'v27tl1 day ot' .Iune,i1 870. M
